Abstract

A verbal input sentence is received from the user in the SR system (102), and a weight is assigned for the level of match for each sentence from the plurality determined sentences according to the content of the input sentence. N (206) sentences having the highest weight are selected from the plurality. If the weight of at least one of the N (206)sentences is higher than the threshold, the sentence having the highest weight is output as the recognized input sentence. If the weight of each selected sentence is lower than the threshold, the weight of each selected sentence is varied according to different predetermined criteria. If the varied weight of at least one of the N (206) sentences is higher than the threshold, the sentence having the highest varied weight is output as the recognized input sentence (209), otherwise an indication that corresponds to unrecognized input sentence is provided.
